Abstract
The method of preventing leakage in outer wall with facing tile includes reasonable design before construction, sorting qualified materials and the following construction steps: 1. controlling the density and saturation degree of mortar and the size of mortar joint; 2. increasing one outer wall port and one inner wall port in the joint between the top of masonry and the ring beam; 3. plastering the wall surface to raise the adhesion between the bottom mortar and the base; 4. preparing door and window openings; 5. constructing flashing in parapet and bearing wall; 6. cleaning and soaking the facing tile; and 7. pointing the exposed joints. The method of preventing leakage in outer wall with facing tile is feasible and convenient in construction.
Description
(1) technical field:
The present invention relates to the method for preventing and treating of a kind of construction techniques, particularly a kind of exterior wall leakage of face tile.
(2) background technology:
In recent years, along with the raising of architectural decoration standard, outer eaves furring brick is decorated general day by day, and still, some buildings come into operation soon, and metope begins to occur seepage.The reason that causes has following several respects situation:
1. design aspect
Some engineering construction figure designs are relatively simplified, the detail structure that has is lacked detailed explanation and drawing, architectural image is novel day by day at present in addition, wall structure changes complicated, but there is not corresponding antiseepage processing node figure in the design, the constructor lacks experience, so that waterproof construction technology is not right, and weak link seeps water easily.
2. material aspect
Brick that has and face brick quality are loose, water absorption rate is excessive, through rain drop erosion and alternate freezing and thawing, causes face brick cracking, blistering, comes off, rainwater easily infiltrates body of wall, present sand is second-rate in addition, and mud content is big, and particle is less than normal, make the masonry mortar label on the low side, the intensity of plastering does not reach requirement yet, causes metope hollowing, cracking to occur, causes seepage.
3. construction aspect
(1) brick works carelessness: along with the raising of architectural decoration, the designer has put on beautiful " overcoat " for building, and people have ignored the function that the masonry antiseepage is divulged psychologically, not too payes attention to laying bricks quality.The mortar that has in the construction is not full; Leading to appears in the masonry that has, empty, blind seam; The pin trick hole that has, cable wind rope and builder's jack drawknot silk are crossed the wall hole and install to be reserved pore etc. and do not stop up tightly etc., cause the body of wall inadequate natural endowment, cause seepage.
(2) jointing is unreal: according to the constructing operation rules, and after brickwork and furring brick have been constructed, must be with the careful jointing of mortar, but some units in charge of construction often deduct this procedure artificially, think that rough ash can replace colluding brickwork joint at the bottom of the face brick.Though the face brick jointing is finished, there are not tight quality problems, water directly infiltrates brick wall from the slit, make indoor formation sheet dark and damp.
(3) base treatment is bad: before plastering, dirts such as the floating ash of surface of wall, incrustation, tongue spot are not removed totally, or the concrete surface interleaving agent do not disposed etc., cause setting course not firm, form sky, split, even face brick comes off, when rainwater jumps on metope, run into body of wall space or fine cracks, just immerse gradually, cause seepage.
(4) it is not careful that thin portion handles the practice: wall concavo-convex position such as the Door and window frame periphery pointing is not closely knit with body of wall, the drip of the stringcourse end opening of balcony, rain cover, the lintel of window, windowsill line, cornice and outstanding metope is not done or is done badly, and parapet, flexible wall, shrinkage joint etc. to locate the flashing node processing improper, all can cause seepage.
